Can you imagine how stinky those would get if that was the case. I googled your question and it appears you can wash kevlar.. I would have thought because it’s layered that wouldn’t be recommended. *shrug*

I’m working a US Army directive right now trying to determine if there is a need to issue these to deployed soldiers; as a veteran of multiple recent combat tours, I can tell you that these are crap, from both a medical standpoint and a soldier on the ground. They’re bulky, they hinder movement, and the area they proctect won’t be saved. These are intended to defeat the groin/artery/lower extremity injuries associated with IEDs, primarily for dismounted soldiers. They are, however, washable, breathable, and made with anti-microbial fabric. Still, almost every combat arms soldier (Infantry, Armor, Scouts, Artillery, etc) thinks theis is a wasted effort and they do NOT want them.
